| Abstract: |
Disclosed is an optically corrected shield for unitary lens eyeglasses or safety helmets. The shield is characterized by an optical centerline and a mechanical centerline, which intersect each other at an angle. The lens is oriented on the head of the wearer by a frame or helmet that maintains the lens in a position such that the optical centerline is maintained substantially in parallel to the normal sight line of the wearer. Lenses are thus provided which have improved optics when mounted in an as-worn orientation such that they exhibit both vertical "rake" and horizontal "wrap." Methods of making the lenses, and eyewear incorporating the lenses, are also disclosed.

What is claimed:
1. A method of orienting a shield in a support for holding the shield in a wearer's field of vision, comprising the steps of:
- providing a support for holding a shield in the wearer's field of vision, said support configured to maintain the shield in a predetermined relationship with respect to the wearer's theoretical straight ahead line of sight;
- providing a shield having a first surface with a first center of curvature in at least a vertical plane and a second surface with a second center of curvature in at least a vertical plane, the shield defining an optical centerline, extending between the first center and the second center, and a mechanical centerline; and
- mounting the shield to the support with upward rake and such that any angle between the optical centerline and the theoretical straight ahead line of sight is no more than about 4 degrees,
wherein the optical centerline is rotated downwardly with respect to the mechanical centerline at a deviation angle of at least about 4 degrees.
